It is also said that the TEL index can assess the ventricular systolic function.
Usually, ventricular systolic function is preserved, whereas diastolic function is impaired.
However, there is still no consensus regarding the ventricular systolic function in these patients.
The ventricular systolic function was performed by subjective analysis and ventricular diastolic function by plotting the pulmonary vein Doppler.
Of the 363 patients, 225 62% did not have LVSD,80 22% had LVSD; the left ventricular systolic function was not assessed in 58 16% Figure 2.
Cardiac resynchronization therapy is based on the concept that QRS prolongation can cause intra-and interventricular dyssynchrony,impairing ventricular systolic function.
SIV-chronic infection results in reduced ventricular systolic function and extensive coronary arteriopathy suggesting an injury mediated by immune cell response.
The patient has evolved in the postoperative period without intercurrence with echocardiogram showing normal ventricular systolic function and no signs of obstruction.
Left ventricular systolic function was considered compromised when its value, calculated by the Simpson method, was lower than 55% of the ejection fraction.
The presence of LVH can lead to heart failure HF with preserved ventricular systolic function, which is more common in elderly female patients with arterial hypertension.
Transthoracic echocardiography revealed normal left ventricular dimensions and systolic function with no left atrial enlargement; furthermore,the right cavities were not dilated, and the right ventricular systolic function was preserved.
Determination of ventricular systolic function and measurement of ventricular volumes can be performed using different noninvasive imaging techniques.
Another remarkable aspect was that the development of irreversibility clearly correlated with the loss of ventricular systolic function observed in 36 patients with Chagas cardiopathy.
In contrast, left ventricular systolic function was similar in both groups, perhaps due to our enrollment criteria, which excluded patients with overt heart failure.
Based on the clinical and echocardiographic findings of shock andseverely depressed left ventricular systolic function Table 1: Ejection fraction 0.20± 0.056, the following rescue protocol was performed.
Left ventricular systolic function was quantified, based on WMI, as: 1 if normal; 1.1 to 1.6 if mild ventricular dysfunction; 1.61 to 2 if moderate ventricular dysfunction; and> 2 if severe ventricular dysfunction.
Likewise LVEF, another established index to assess left ventricular systolic function is the positive dP/dt, also used as a predictor of mortality in patients with CHF.
Such patient, probably had dilated cardiomyopathy secondary to hypertension, moderate dilation of the left ventricle,as well as preserved right ventricular systolic function and no signs of pulmonary hypertension.
CMR is considered a reference standard for ventricular systolic function, including the analysis of regional wall motion, mass, and volumes, and estimation of ejection fraction.
Mitral regurgitation was diagnosed and quantitatively graded by color Doppler,with additional analysis of positive dP/dt as a measure of ventricular systolic function, calculated by continuous wave Doppler, according to the literature.
Most pediatric studies publishedhave focused on ventricular systolic function assessment; therefore, the effects of chronic ventricular pacing on diastolic function are not well known, even less in children with CHD.
The aim of this study is to assess the relationship between interstitial collagen content, measured by right ventricular septal biopsy, and right and left ventricular systolic function in ICM patients with varying degrees of ventricular dysfunction.
The analysis by the strain technique,a parameter used to assess the right ventricular systolic function measured at the basal segment of the free wall of the right ventricle showed a value of 15% NV 27± 6%, indicating systolic dysfunction of this chamber.
In an attempt to modulate the massive sympathetic activation caused by scorpion envenomation and minimize the need for positive inotropic support with beta-adrenergic agonists,we have followed an antiadrenergic rescue protocol for acutely depressed left ventricular systolic function.
Moreover, in patients with Chagas' disease and preserved left ventricular systolic function, the norepinephrine concentration is lower, compared to that in coronary artery disease patients.
Left ventricular systolic function, analyzed by the ejection fraction on echocardiogram, was similar between groups 66.1±10.1% vs. 68.6±5.4% for HD patients and controls, respectively, P 0.167, but diastolic dysfunction was more prevalent in HD patients 77% vs. 42%, P 0.004.
However, it must be highlighted that the utilization of imaging methods that evaluate left ventricular systolic function for measuring indirectly the myocardial infarct extension is subject to various factors that can lead to inaccuracy.
The left ventricular systolic function may be analyzed using the M-mode, the two-dimensional mode with techniques such as strain, strain-rate and tissue tracking which analyze ventricular longitudinal deformation, and also using the three-dimensional echocardiography.
In DCM group,the correlation between conventional echocardiographic parameters of ventricular systolic function and GS was positive for the ventricular volumes obtained by RT3DE and negative for the LVEF and S Figure 3.
The left ventricular systolic function was estimated by the ejection fraction EF according to Teichholz's formula, percentage of left ventricular circumferential shortening?D%, calculated using the formula[LVEDD- LVESD/ LVEDD] x 100, and the velocity of circumferential fiber shortening Vcf.
